have invented new an a specification.

to nut llocks and A are detachably connected` and so designed as. to loosely retain means which constitutes the g av locking assem essential part in effectinL blage; to produce a nut of separable sections which are designed to retain a wedge for use, and allowing the removaly and'substi` tution o1c the wedge when the occasion demands; to combine 'a screw threaded headed bolt having `flexible portions with a nut having a wedge disposed diametrically of vits screw threaded bolt hole, and being relatively movable, which wedge serves to flex the said flexible portions of the bolt to effeet a locking engagement of the nut with l the bolt when the nut and bolt are employed for the purposes for which nuts and bolts are employed. `With these vand other ob# jects in view the invention resides in the particular provision, p'loyment of parts hereinafter more fully described and illustrated in the accompanyino drawing, in which: v

igure 1 is aside elevation ot a bolt and nut of the present invention.

Figure 2 is an 'enlarged central longitudinal sectional view through the nut and a part of the bolt.

Figure 3 is a transversevsectional view taken on the line 3-3, Figure 2.

Figure i is a sectional view oit tbe nut 'with the wedge removed.

Figure 5 is a view similar to the view shown in Figure. 2 but the present view is taken in a plane ata right angle to the plane through which the section of Figure 2 wasv taken.

Figure 6 is a perspective view of the wedge detached from the nut.

Referring now more particularly to the several views 'or all ot the details it will be manifest that, the device of the ypresent invention includes a bolt 10 having a head in Nut locks, of-

ects or' the present inv-en"-v locking engagement of the nut construction and emof the bolt 10 as the nut placed on the screw threaded end of the the wedge serial No. sazia l 11 at one end, and which is screw threaded as at 12 at `the other end, and which'isf bifurcated to provide flexible portions 313,] 13. The device also includes aznut 14 com# d prising sections 15 and16.'` The -.section=}15' v y provided jwith j a ybore -17 Ahaving screw,v t

sonprovided with'a threads20..`

is threadsplS, and it is a bore or bolt hole 19 with screw The. section 15 on theout'side" has nat faces..

`which affords f means whereby: thev section may be readily manipulated by a tool such as av wrench. kThe section 160i the -nut has anipple or reduced part 21 which is 'screw threaded as at .22 andv which part-211itsf1 the bore 17. The section"`16l is alsov pro.` vided `with 'abolt-holef 'which is .screw threaded, as at 241* -Thefsection 16 like the section 15 has fiat aces'25so as to accoinmoe. datea tool;l The sections y15 and 16 when brought together ormanannular wayf26- see Figure 4. l e

As stated before it is one of the objects of the present invention to employ means l or'fieXing portions of the bolt to ,effect the withthe said bolt. In the present instance there isem-` fployed a wedge 27 tapered yfrom top to'bottom. The wedge'is projections 28,4 28. The wedge isfslightly lessin width than the diameter of the-bolt ,provided with lateral.

and consequently "less than the diameter of4` bolt hole in the section 16. `The wedge is'retained by the bringing tions are arcuate to conform to thesi'de wall .j

together ofthe sections 15 and 16, as a part of the nut 14:, and.

of the way 26, and ybecause of thisand the t fact that the projections are *directly opposite each other the wedgey is maintained diametrically of thebolt hole 23 of the section 16'.l It 'follows the wedge readily inds,

`bolt.' As the nut is screwedhome moves down between the portions 13,` 13. When the section 16 isbrought ag'ainsta thing to be secured, the section' 15 `may be moved relatively to the section `16to cause the wedge to move still further into the kerf -or space between the portionsA 213, 13

from this that the nose ojl-` `1,00

its way into the kerf 14 in its entirety is l thns it'orcing the said portions 13, 13 out- X'vardly into engagement With the nut seotions and girincpally the section 16.

.F rom the foregoing` it will be manifest that, the Wedge is loosely retained in the nut; the Wedge is removable and therefore replaceable;,the employment of a sectional nut allows the ready application of the bolt and nut and the effeotion of a loelzinp` engagement of the parts; and that aside from the locking engagement of the use of the Wedge the sections 15 and 16 afford the advantages of jam-nuts.

what is claim-ed :is:

l. The combination With a screwy threaded headed bolt having relatively flexible portions at the screw threaded end thereof7 of a sectional nut which coacts withv said bolt, and means removably Carried by the vnut for flexing said portions into engagement with said nut.

2. The combination With a screw threaded headed bolt having relatively flexible. portions at the screw threaded end thereof, of a sectionaljnut which coacts with said bolt, and a Wedge loosely connected to said nut for exing said portions into engagement With said nut.

v22'. The combination with a screw threaded .headed bolt having relatively Hexible 1 ,leaner portions at the screwY threaded end thereof, et a sectional nut which Coacts with said bolt, and a Wedge loosely connected. to said nut and disposed diametrieally in the bolt hole thereof for flexing said portions into engagement with said nut.

t. F or a bolt having flexible portions, a sectional nut removably carrying a relatively rnovable Wedge for flexing the ilexible portions of said bolt.

5. F or a bolt having flexible portions, a sectional nut removably carrying a relatively movable Wedge for flexing the flexible portions of said bolt, and means for maintaining the Wedge disposed diametrically of the bolt hole of said nut.

6. F or a bolt having flexible screw threaded portions, a nut of separable sections the said sections forming an annular Way, a Wedge having lateral projections extendable in said Way and-allowing axial relative movement of the Wedge with respect to the nut and substantially preventing longitusignature.
